Smart Line Modules (16 kW und 36 kW) with internal air cooling
3.6.1
Description
The Smart Line Module is an unregulated infeed/regenerative feedback unit. The Smart Line
Module supplies the Motor Module(s) with an unregulated DC voltage at the DC output. In
the infeed mode the Smart Line Module exhibits the typical current and voltage waveforms of
a 6-pulse diode rectifier bridge.
In feedback mode, the current waveform is square waved. Feedback can be deactivated by
means of parameterization because like the Active Line Modules, these Smart Line Modules
are equipped with a DRIVE-CLiQ connection.
The DC link starts precharging as soon as the supply voltage is applied and is independent
of its phase sequence direction. Load can be applied to the DC link after the modules have
been enabled. An optional main contactor is required for disconnecting the voltage.
Smart Line Modules are suitable for direct operation in TN, IT, and TT systems. The Line
Modules have an integrated overvoltage protection function.
3.6.2
Safety information
Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been disconnected.
The protective cover may only be opened after this time has expired.
When opening the protective cover for the DC link, you must activate the release.
A suitable tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be further used otherwise this could result in secondary
damage or accidents.
A sufficiently high supply short circuit power is required for tripping the fuses within the
predefined time in the event of a ground fault. The ratio of line short-circuit power to rated
power must be ≧ 70. If the line short-circuit power is too low, the tripping times increase to
an unacceptable level (e.g. fire is possible).
